I wire transfer thousands to merchants and usually only have to pay about 15 dollars to wire the money. If they take bank to bank its better then doing a western union transfer. Its simple and you can ask evertek. They are a very very reliable supplier.
Sending money via TT has got some risks into it. I have been payng my suppliers via TT and I have set it up through my bank here in Australia. With ANZ, they can give you 2 limits from a business classic account, 1. = $5000AUD and 2. = $10,000AUD. Both limits have a TT fee of $24AUD. And best of all yo can send that off via online TT. If you were to walk into a bank (ANZ) they charge about $35AUD for the TT.
